> Everyone working in enterprise software development has known about the power of this language for well over a decade. But, you won't find a single YC startup that would admit to using it. Not sure about that. Maybe there are? If you do web or mobile apps, C# would be an excellent choice. Go would be also an excellent choice for web. For AI I wouldn't use C#. Even though it has excellent ML libraries, most research and popular stuff is done using Python and pytorch, so that's what I would chose. For very low level, I'd take C or Zig. But I don't know many startups who are into very low level stuff.
